Kestrel 4500 Wind / Weather Meter

For aviation applications, wind direction along with wind speed can be critical.  The Kestrel 4500 does just that with its built in digital compass. But it doesn’t stop there. It also calculates density altitude, crosswind and headwind/tailwind with reference to a user-set target heading and stores the information along with all the other environmental readings in its 1400 data point memory.

Pair the 4500 Wind Meter with the Kestrel Vane Mount and you have a data-logging weather station that sets up in seconds and rotates in the slightest of breezes. Did we mention that the whole kit is the ultimate in portability? It packs down into a 2 x 6 inch pouch and weighs under 8 ounces.

Every Kestrel Meter features a large, 1” impeller mounted on a sapphire jewel bearing, which means it starts rotating with the slightest puff of air – 0.3 mph to be exact! And this unique impeller is user-replaceable, too, which means it can easily be replaced if it is damaged or worn.

If your application demands regular calibration, simply pop in a new impeller and the Kestrel Wind Meter is restored to like-new factory calibration standards. The Kestrel 1000 can easily be switched between mph, km/h, ft/min, m/s, knots and Beaufort.
